This study explores the inspection of bolted connections in wind turbines, specifically focusing on the application of Phased Array Ultrasonic Testing (PAUT). The research comprises four sections: Acoustoelastic Constant calibration, high tension investigation on bolts, blind tests on larger bolts, and Finite Element Analysis (FEA) verification. The methodology shows accurate results for stress while the bolt is under operative loads, and produces a clear indication of when it is above these loads and beginning to deform. PAUT emerges as a promising tool for bolt inspection, offering multiple imaging modes for simultaneous stress monitoring and defect detection. The study advocates for PAUT as a robust method to enhance wind turbine safety, longevity, and future in-situ testing.
本研究探讨了风力涡轮机螺栓连接的检测，特别关注相控阵超声检测（PAUT）的应用。该研究包括四个部分：声弹性常数校准、螺栓的高张力研究、大型螺栓的盲测以及有限元分析（FEA）验证。该方法在螺栓承受工作载荷时能给出准确的应力结果，并能清晰显示何时超过这些载荷并开始变形。PAUT成为螺栓检测的一种有前景的工具，提供多种成像模式用于同时进行应力监测和缺陷检测。该研究主张将PAUT作为一种可靠的方法来提高风力涡轮机的安全性、使用寿命以及未来的现场检测能力。
